IMPROVEMENT IN SULKY-PLOWS.

Specification forming part of Letters Patent No. 211,662, dated January :28, 1879 application filed March 27, 1878.

'To all whom it may concern.-

Beit known that I, FRANKLIN B. HUNT, of Richmond, county of Wayne, and State of Indiana, have invented certain Improvements in Sulky-Plows, of which the followingis a specication:

My invention relates to a series of novel devices and combinations of devices, hereinafter fully described and set forth in the specification and claims.

Figure l of the drawings is a side elevation, the right wheel being removed. Fig. 2 is a rear elevation. Fig. 3 is a' rear view of the crank and furrow-wheel axles connected by means of the seat-arch. Fig. 4. is an inverted front view of the seat-arch with the furrow- Wheel axle attached. Fig. 5 is a view of the seat-rest and foot-rest combined and made in one piece. Fig. 6 is a view of the lever attached to the .detachable segment. Fig. 7 is a side view of the quadrant. Fig. 8 is an inside view of one of the pivoting-blocks. Fig. 9 is a perspective of the combined bearing and socket for the tongue, detached from the seatarch. Fig. 10 is a view of the leveling-block attached to the plow-beam.

A is the seat-arch, having the furrow-wheel axle B rigidly attached thereto, and arranged below the line of the crank-axle C, in order to adapt one wheel to the furrow. The pivotingblocks F are fitted to the part e of the crankaxle, and are provided with the bearings a for the circular leveling-block E, attached to the plow-beam D, which is curved downward to form a standard for the plow. The levelingblock E is provided with lugs E to receive pins to hold it in place on the beam.

^ By means of this arrangement of the pivoting and leveling blocks the plow-beam is permitted to vibrate longitudinally and laterally, and the same device pivots the plow-beam to the crank-axle, and the leveling-block attached to the plow -beam operates, in conjunction with the furrow-wheel axle, arranged below the line of the crank-axle, to level the plow under all circumstances. For instance, in striking out a land both wheels run upon the land, and the leveling-block levels .the plow accordingly, and is tightened or clamped in position by means of the upper bolt in the pivoting-blocks and held rmly'. After the rst furrow has been laid out and the wheel takes the furrow, the leveling-block attached to the beam is again brought into requisition to level the whole, according to the depth of furrow itis desired to turn. The leveling and pivoting blocks are cast of suitable dimensions to apply directly to the plow-beam and crankaxle without fitting, and are held firmly in place by means of the lower bolts passing through the pivoting-blocks, the upper portions of the pivoting-blocks standing sufficiently apart to admit of being clamped upon the leveling-blocks by mean of the upper bolt.

rlhe seat-arch is held in place upon the crank-axle by means of the cap G and the bolts passing through it, as seen in Fig. 3. The end I of the crank-axle passes through the seat-arch above the furrow-wheel axle at H. Thus it will be seen that the crank and furrow-wheel axles are combined and arranged to each support the other, and connected by means of the seat-arch, and yet operate entirely independent of each other, the one serving to carry the furrow-wheel, and the other, operating to carry the land-wheel, at the same time serves to raise and lower the plow through the means of `the segments J K and lever L, held in place when adjusted by means of the quadrant M, the rear end of which is attached to the seat-arch by means of cleats and a single bolt, as shown in Fig. 2. The forward end is attached to the tongue-bearing by means of the bolt, which holds the tongue in place, passing through it, as seen in Fig. l.

The lever L and segment K may be detached from the lug L' to allow the plow to play automatically in freeing itself from obstructions, when desired to work in that way, or the plow may be adjusted and locked in the ground. The lever L has a backward movement in raising the plow, the crank axle and lever being connected by means of the segments J K, provided with ordinary cog-teeth, which always remain in mesh, and the radius of the leversegment K, being less than that of the crankaxle segment'J, gives compound leverage in raising the plow, so that any boy of suitable age to drive a team can easily operate the plow.

Segments attached to a crank-axle have been used in connection with a lever having a catch or pawl attached to said lever. I operate the` crank-axle segment by means of a like segment provided with cog-teeth to remain in mesh'fat all times, and attached to the lever. Thus the stress in raising the plow is equal at all points. The segment K is attached to the seat-arch by being pivoted to the lu g L' attached to the arch, and the lever extends upward therefrom in convenient reach of the driver on his seat O. v The seat-arch is provided with double bearingsl? for the tongue P. These bearings have attached to them the sockets It, to receive and support the end of the tongue, and side iianges S, by means of which the tongue is held in place, by means of a single bolt passing through the tongue and the front end of the tongue-bearings. The double bearin gs are for the purpose of adapting the sulky to either two or three draft animals, as may be desired, by simply changing the tongue from one bearing to the other. When the tongue is in the center bearing a block, 0', is placed in the other bearing, as shown in Fig. l, to support the front end of the quadrant. The only cost of adapting the sulky to two or three animals at will is the weight of metal in one bearing, and the only cost of leveling the plow both ways and under all circumstances is the weight of metal in the leveling-block attached to the plowbeam, the pivoting device to pivot the plowbeam to the crank-axle being no more expensive than the ordinary pivoting apparatus now in use. The combined bearings and sockets are cast as an integral part of the seat-arch, and are plainly shown in the detached view, Fig. 9. The tongue is rigidly attached to the furrow-wheel axle through the means of the seat-arch and ton gue-bearings, to guide the sulky with precision, and allow the crank-axle free play independent of the tongue, the crankaxle being supported and held in place entirely by means of the seat-arch. There is a lug, N, (seen in Figs. 2 and 3,) attached to and cast as an integral part of the seat-arch, and from this lug the combined rest shown in Fig. 5 is suspended, and made adjustable by means ot bolts passing through the slots z' and into the seat-arch, and allowing the adjustable seat and foot-rest to vibrate laterally upon the lug N. The seat and foot-rest may be allowed to play loose and adjust themselves according to circumstances, or may be tightened and held in any required position by means of the bolts passing through the slots t' in the seatt rest.

The seat O is att-ached to the seat-rest by means of a single bolt passing through the spring-standard V, attached to the seat.

The furrow-wheel axle may be cast into the seat-arch.

The rear pivoting-block may be graduated, and a pointer attached to the rear lug, E', to determine the level of the plow at any required depth of furrow, and the bearing-surface of one or bot-h sides of the beveling-block may be corrugated, and thc bearing-surface of the pivoting-blocks corrugated to correspond, if necessary, to hold the plow rmly in place when leveled.

The laterally-adjustable seat and foot-rest operate not only in conjunction with the leveling-block, but with the furrow-wheel axle arranged below the line of the crank-axle as well, for the general purpose ofi leveling the whole machine to suit any possible circumstance or requirement.

The combined rest F and R (shown in Fig. 5) is cast in one piece, with the holes and slots ready for use without any fitting. The seatarch is the central construction, to which all else is depended except the plow-beam, and that part is indirectly depended through the crank-axle and pivoting-blocks.

Thus it will be seen that the crankand furrow-wheel axles are attached to the seat-arch as well as the ton gue-bearin gs, the beariu g for the quadrant, segment K, and the lng N, from which the adjustable drivers seat and foot-rest are suspended. all the requirements of a perfect sulky-plow, and is very inexpensive to build, having less {itting than any sulky now made, the parts being nearly all cast ready to go together, and the whole machine being adjustable in every possible direction that a sulky-plow can be required to be adj usted; and, further, all the adjustable parts and devices can be allowed to play loose,

or be tightened in whatever position may be required, at the will of the operator. 4
